Planetary defense with the Double Asteroid Redirection Test (DART) mission and prospects

Nature Communications, 2023
NASA’s Double Asteroid Redirection Test (DART) mission intentionally impacted the asteroid Dimorphos on September 26, 2022, and this kinetic impact changed Dimorphos’ orbit around its binary companion Didymos.

Asteroid Family Associations of Active Asteroids [PDF]

The Astronomical Journal, 2018
Abstract We report on the results of a systematic search for associated asteroid families for all active asteroids known to date. We find that 10 out of 12 main-belt comets (MBCs) and five out of seven disrupted asteroids are linked with known or candidate families, rates that have ∼0.1% and ∼6% probabilities, respectively, of occurring ...

Successful kinetic impact into an asteroid for planetary defence [PDF]

Nature, 2023
The impact of the DART spacecraft on the asteroid Dimorphos is reported and reconstructed, demonstrating that kinetic impactor technology is a viable technique to potentially defend Earth from asteroids. Although no known asteroid poses a threat to Earth

Ejecta from the DART-produced active asteroid Dimorphos [PDF]

Nature, 2023
Some active asteroids have been proposed to be formed as a result of impact events^ 1 . Because active asteroids are generally discovered by chance only after their tails have fully formed, the process of how impact ejecta evolve into a tail has, to our ...

Soluble organic molecules in samples of the carbonaceous asteroid (162173) Ryugu

Science, 2023
The Hayabusa2 spacecraft collected samples from the surface of the carbonaceous near-Earth asteroid (162173) Ryugu and brought them to Earth. The samples were expected to contain organic molecules, which record processes that occurred in the early Solar ...
